Pressure Gauge Meter Control Valve End Water Test Equipments Fire Equipment Accessories DN25 Ball Value Male Female Thread

2, product featuresIt consists of pipe fittings such as pressure gauges, copper control valves, and standard flow orifice plates. 14MPa water pressure after assembly, no leakage for 3min3, the main function1) The most unfavorable part of each protection zone of the simulated sprinkler system. When the nozzle is working, the linkage and reset performance of the water flow indicator, alarm valve and pressure switch2) Test the working medium conversion time of the dry, pre-action, foam spray system at the least forest level, such as gas-water, water-foam3) It is convenient for the flushing and water exchange maintenance of the pipeline in the future.4) Show the hydrostatic pressure and spray pressure of the most unfavorable throwing nozzle4, installation1) It should be ensured that the end water passing device is discharged into the sewer pipe in the manner of outlet flow.2) The flow outlet of the end water test device with the same minimum flow coefficient nozzle as the protection zone should be selected, K=80, 115, 200.3) Inlet interface: K=80, 115 is R1"; K=200 is R2.
